Dear Hiring Team,

Netflix's recommendation engine drives 80% of viewing decisions — that's exactly the kind of impact I want to work on. At Spotify, I led the personalisation team that improved playlist CTR by 34% for 4M users using causal inference at scale.

I'd love to show you how the geo-experiment framework I built...

No writing skills required. The AI does the heavy lifting — you do the final polish.

01

Paste the job description

Drop in the full job posting — title, responsibilities, requirements. The AI reads it like a senior recruiter and extracts every keyword and signal.

02

AI matches it to your background

Connect your Documentgate resume or paste your experience. The AI identifies your strongest matching points and builds your value proposition.

03

Get a tailored letter in seconds

A personalised cover letter is generated — with your metrics, the company name, the role's keywords, and a compelling narrative woven throughout. Edit, regenerate, or download.

The AI difference, in plain sight

Same candidate. Same role. The AI version reads the job description and writes to the company — not at it.

Netflix's recommendation engine powers 80% of content watched — I want to be on that team.
At Spotify, I built an ML model that improved playlist CTR by 34% across 4M users in 6 months.
Your job posting mentions 'causal inference at scale' — I led a geo-experiment framework used in 12 markets.
I'd love 20 minutes to walk through how I'd approach your cross-session personalisation challenge.

AI vs. writing it yourself

Manual cover letters take 45 minutes and still read as generic. The AI takes 20 seconds — and sounds more like you.

Not just AI — smart AI

Most AI tools paste your resume into a template. Ours reads the job description and constructs your case from the employer's perspective.

Deep Job Description Analysis

The AI reads every line of the job posting — extracting required skills, preferred qualifications, tone, and company values — before writing a single word.

Hyper-Personalised Output

No templates, no generic openers. Every letter references the specific role, company, and why your unique background makes you the right fit.

Built-In ATS Optimisation

Every generated letter contains the exact keywords from the job posting so it passes automated screening before a human ever reads it.

Tone & Length Control

Choose from professional, conversational, enthusiastic, or concise. Set the length from a sharp 3-paragraph letter to a detailed page-long narrative.

Recruiter-Eye Preview

See how a recruiter scans your letter in 6 seconds — the AI highlights the headline, the match signal, and the call to action a hiring manager notices first.

One-Click Regeneration

Not happy with the angle? Regenerate with a different hook, focus, or tone instantly. Unlimited attempts — always free to perfect.

AI-generated examples by role

See how the AI tailors every letter to the specific company and role — no two letters are the same.

Their words, not ours.

"I was applying to 30 jobs and dreading writing 30 different cover letters. The AI wrote each one in under 20 seconds — each one sounded like me, but sharper."

Daniel K.
Data Engineer at Databricks

"I was skeptical. Then I pasted a job description and it mentioned that Linear values 'taste and craft' — the AI wrote directly to that. I was floored."

Sophie R.
Product Designer at Linear

"My previous cover letters were boilerplate. This AI referenced the exact product expansion mentioned in the JD. I got a reply the same day."

Carlos M.
Account Executive at Rippling
